He tweeted: "Sources confirm that Meghan's wedding dress is finished and safely hidden at Windsor Castle until the big day".
The bride and groom are: Prince Harry, 33, officially known as Prince... This week, Madame Tussauds London unveiled a wax figure of Prince Harry's betrothed, and for once, the figurine actually does its subject justice. This isn't the only royal wedding-related story doing the rounds, as Legoland Windsor has created a attractive miniature model of the wedding, complete with a miniature Windsor Castle.
He said: "I've seen him grumpy".
The waxworks will go on public show the day before the wedding.
"The carriages are used in official and ceremonial state events, such as Coronations, Royal Weddings and State Visits".
Capt Calder, 32, who has dual UK/US citizenship, said his unit would be training hard ahead of the wedding and he reacted with "stunned surprise" when he found out he would play such a key role.
Her parents are expected to arrive in time to get to know the family members of Prince Harry and interact with them before the wedding.
Harry's choice of Markle, an American former actress and campaigner for gender equality, makes the wedding even more special.
Millions of people are estimated to watch the wedding live.
In a documentary on United Kingdom channel Sky One, Gina Nelthorpe-Cowne discussed a trip she took to the Cayman Islands with Meghan. The programme - featuring Richard Goulding as Prince Harry and Kathryn Drysdale as Meghan Markle - is billed as "an outrageous satirical comedy to celebrate the royal event of the year". Doria Ragland flew to London to help her daughter prepare for her upcoming wedding to Prince Harry, Us Weekly confirms.
It looks like it's not just the run-up that sounds stressful however, with Harry and Meghan having a lot of jobs and duties to carry out on the actual day.
